------- Comment #2 from epperly2 at llnl dot gov 2007-06-01 20:53 -------
To avoid depending on system #include files, the example has
typedef unsigned int size_t;
hardwired in the code. This may be an incorrect definition for some platforms.
Oddly enough, if I delete NextClass and make TestClass inherit directly from
BaseClass, the program no longer segfaults.
I am not sure if all the features of this example are strictly necessary. I
basically created a new program from scratch that has the same characteristics
as the original 100+K program, and I added things until it reproduced the same
behavior.

I am thinking you are volating C++ aliasing rules (though if you convert the
static casts over to placement news it will not work either but that is PR
29286).

------- Comment #5 from epperly2 at llnl dot gov 2007-06-01 21:24 -------
In response to comment #4, I may be violating C++ aliasing rules, but I don't
see how that explains the behavior I am seeing and where I am seeing it. How
could aliasing analysis give the compiler permission to skip _local_result's
constructor? If it assumed that the operator= method didn't read from the left
hand side, it might make such a mistake.

I've simplified the sample case that demonstrates the problem, and it has *no*
casting in C++. In C, it casts the result of malloc to the appropriate pointer
type.

The function pointer in RefCount_t can be removed too
This is a smaller program that removes a couple function pointer casts. At this
point, I don't think there are any aliasing problems.

I tried test_4.tar.bz2 on my home PC whose details are below. I had to change
the definition of size_t to "typedef unsigned long size_t;" in RefCount.c. It
failed just like the other system I tested it with.

Note that making the inheritance non-virtual and fixing up
TestClass::TestClass(TestClass::ior_t*) to initialize NextClass instead
of BaseClass fixes the problem as well.
So this may be a C++ frontend problem with virtual inheritance or an
invalid testcase as well.
(What happens if you initialize BaseClass from TestClass, but not NextClass
-- if NextClass is default constructed then it will default construct
BaseClass as well? C++ language lawyer question.)

It looks like 12.6.2/5-6 specify it enough to make the testcase valid. The
BaseClass is only once initialized by the most derived object initializer
specification.

Both bug32182 and test_4 work for me with pre-4.3.0 on i686-pc-linux-gnu, so
I'm going to set known to work for 4.3.
